"The thesis evolved into the first biographical-history of General Thompson and the submachine gun that was published by the Macmillan Company as The Gun That Made The Twenties Roar. It received favorable reviews in Newsweek, The Washington Post s book section, and more than a dozen newspapers that had book columns at the time. (A few years later a photocopied edition of the original book was printed by Gun Room Press to accompany a longer-barreled semi-automatic version Thompson then being marketed by Numrich Arms, and it included an additional chapter on the Numrich gun by George Nonte that is not included in this second edition.)Since then any number of books and articles have retold the Thompson story, but the only one that greatly expands on this edition, especially in manufacturing details, is The Ultimate Thompson Book, published in 2009 by Tracie Hill, founder of The American Thompson Association. I want to thank Tracie for most of the additional photos that appear in this edition. I also want to thank David Albert, former president of TATA, for putting me in touch with Chipotle Publishing Company which presents this second edition, one hundred years after the founding of the Auto-Ordnance Corporation. It is expanded with boxes and an additional chapter that updates the original book that was published in 1969."
